IMPROVEMENT IN LIDS OR COVERS FOR VESSELS.

Specification forming part of Letters Patent No. 221,150, dated November4, 1879; application filed November 21, 1878.

To all whom it may concern:

Be it known that I, JAMES C. BOYLE, o the city of Sycamore, in thecounty of DeKalb and State of Illinois, have invented certain new anduseful Improvementsin Lids or Govers for Vessels; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification, and in whicl1-- Figure 1 is aperspective view of my improved lid for closing the receiving-orificesof barrel-churns, tanks, boxes, 82c. Fig. 2 is a central verticalsection of same; and Fig. 3 is a vertical-section of a barrel-churnmounted upon a suitable frame, showing the lid secured in place.

Corresponding parts in the several figures are denoted by similarletters of reference.

This invention -appertains to certain improvements in lids for closingthe receivingorifices of barrel-churns, boxes, tanks, 860.; and itconsists,first, of a metallic ring or plate provided with ears andthumb-screws, in combination with a lid having lugs; and, secondly, ofthe lid having a metallic ring, with its outer portion bent downwardlyto form, with the outer edge of the lid, a recess to receive a gasket ofcork or other suitable packing, substantially as hereinafter moreparticularly described and claimed.

Heretofore lids for barrel-churns have been held in place by rodsentering perforated ears upon the outer plate or ring, operated by aneccentric, I which, in the operation of churning, have been found to beunsafe, by working loose and spilling the whole or part of the contentsof the churn.

The object of my invention is to remedy this defect, and also to furnishthe trade with a'simple, durable, and efficient lid at a small cost.

In the annexed drawings, A marks a wooden lid,- to which is secured, bymeans of the crucial arms I) and lugs b, the metallic ring B, having itsouter portion bent downwardly to form, with the outer edge of the lid A,a

recess to receive a gasket of cork, rubber, or other suitable packing,D, said packing resting upon the rib or bead 0, formed on the innersurface of the metallic ring or plate 0.

On theouter edge of the ring B are lugs B, the purpose of which will bepresently set forth.

Secured to the metallic ring 0 are a suita= ble number of ears, E havingeach a shoulder, a, projecting from the upper part of said ears, toform, with the surface of the ring 0, a recess for the reception of thelugs B of the ring B. These shoulders e are provided with a femalescrew, which receives a suitable thumb-screw, e, the purpose of thelatter being to secure or hold the lugs B under the shoulders e.

p A knob, F,'is secured to the lid A, so that the latter can be easilyhandled.

The outer ring, (1, rests in the groove made in the staves of a barrelthat receives the ordinary head, as clearly shown in Fig. 3. This figureshows the lid secured in place in an ordinary barrel-churn mounted upona suitable support or frame.

Operation: To remove the lid A from the outer ring, 0, loosen thethumb-screws e turn the lid slightly to the left, which will remove thelugs B from under the shoulders 0, when the lid can be raised from thering 0. To secure the lid in place, rest the lid A upon the ring 0, sothat the lugs B are in front or to the left of the shouldered ears E;turn the lid slightly to the right, which will bring the said lugs underthe shoulders c of. the .ears E, when, by means of the thumb screws epressing down upon the lugs, the lid will be securely held in place.

It will be seen that, by the gasket of cork or other packing beingtightly pressed down on the rib or bead c of the ring 0 by means of thethumb-screws e acting on the lugs B, a tight joint is formed.

When it is desired to use my lid upon box churns, tanks, &c., the outersurface of the metallic ring or plate 0 is adapted to conform in shapeto the box, &c., and is screwed or bolted to such receptacle, a rubberor otherpacking having first been placed between the and tlIHIDb'SCIOWSc, substantially as shown receptacle and ring to insure a tightjoint.and described. 1

Having thus described my invention, whatI In testimony that I claim theforegoing as claim, and desire to secure by Letters Patent, my own Ihave affixed my signature in presis once of two witnesses.
